Technical data: Wheel diameter [mm]: 180 Tread width [mm]: 47 Fixed set height [mm]: 210 Permissible load [kg]: 300 Set / wheel weight [kg]: 2.18 Hole spacing [mm]: 80x105 o10 Bearing type: Ball ZABI aluminum-polyurethane wheels with a fixed housing consist of an aluminum wheel body with a permanently bonded polyurethane tread and a sturdy pressed steel housing. The wheel in this housing is mounted on a bushing and is mounted to the housing cup using a bolt and nut. Fixed casters do not rotate. This type of housing provides the device with straight-line stability. Aluminum-polyurethane wheels and casters are characterized by high load resistance. The wheels are resistant to discoloration. They operate quietly and absorb vibrations and impacts. They are characterized by low rolling resistance. Aluminum-polyurethane wheels and casters can be used in temperatures ranging from -20°C to +80°C. The standard wheel tread hardness is 92 Shore A. They are characterized by high resistance to grease, natural oils, gasoline, and solvents, which increases their application range. Aluminum-polyurethane wheels and casters are available with ball bearings. The operating noise level and the floor protection level of aluminum-polyurethane wheels and casters are rated as good. **
